Knowledge in the World is a history and celebration of those who created the most ground-breaking and remarkable publishing phenomenon of any age. It tracks the story from Ancient Greece to Wikipedia, from modest single- volumes to the 11,000-volume Chinese manuscript that was too big to print. It looks at how Encyclopaedia Britannica came to dominate the industry and how an army of ingenious door-to-door salesmen sold their wares to guilt-ridden parents. It explains how encyclopaedias have reflected our changing attitudes towards sexuality, race and technology, and exposes how these ultimate bastions of trust were often riddled with errors and prejudice. With his characteristic ability to tackle the broadest of subjects in an illuminating and highly entertaining way, Simon Garfield uncovers a fascinating and important part of our past, and wonders whether the promise of complete knowledge - that most human of ambitions - will forever be beyond our grasp.
